Goalball is a unique sport for visually impaired individuals, where two teams of three players throw a ball with bells inside it towards the opponent's goal. In terms of synonyms, the sport is commonly referred to as B1 ball, visually impaired handball, and soundball. Additionally, some cultures have their own terms for goalball, like Finnish goalball, which is known as maalipallo. There are also variations of the sport, such as beach goalball, which replace the traditional indoor court with sand. Regardless of the name or form, goalball has been a popular sport among visually impaired athletes since its creation in 1946.
